The present invention relates to improvements in dispensing machines and has for an object the dispensing of beverages and the storing and selling Of package ice cream and the like.

Another object of the machine is to provide a mobile dispensing machine so constructed and arranged that it may be serviced by a single attendant and pushed about from place to place by the same attendant for the purpose of the distribution and sale of bottled and fountain soft drinks, ice cream and the like.

A further object of the invention is to provide a transportable machine for the dispensing and vending of fountain drinks, ice cream and the like in which the various units are compactly as sembled into a unitary vehicular machine to bring all such units within small compass not only for the embodiment of the same as separate integers in a composite vehicle, but also to aid n the prompt service of the beverages and ice cream due to the fact that suchunits are closely assembled for quick and easy access by a single attendant.

A still further object of the invention resides in the provision of a vehicular fountain and ice cream storage receptacles in which the mobile character of the apparatus is screened and largely secreted and the device as a whole given an appearance of a stable and installed bar or soda fountain and in which further provision is made for the protection of the side Walls and included. refrigerating units and other parts which are susceptible to damage from collision with other vehicles in encountering the hazards of vehicular traflic.

With the foregoing and other objects in view the invention will be fully described hereinafter and more fully pointed out in the appended claims.

Figure 10 is also a vertical section taken on the line ill I 0 in Figure 7 a Figure 11 is a fragmentary horizontal section taken through a corner portion of the framework on an enlarged scale.

Referring more particularly to the drawings,

the

the machine comprises generally .a wheeled chassis, a superstructure thereon and a body carried on the superstructure in which is contained the compartments and receptacles for the ice cream and the beverage syrups.

The chassis is composed generally of two iongitudinal rails or beams i5 and it which are spaced apart and arranged in substantial parallelism. Such beams or rails and the other beams or rails composi'ng the chassis and superstructure are made advantageously of angle iron in cross section; As shown in Figure 5 the horizontal webs of the longitudinal beams i5 and I6 are turned inwardly with the vertical webs turned upwardly in such wise that these longitudinal beams i5 and it are peculiarly located and arranged to receive therein the transverse beams I8, l9 and 28. As shown in Figure 4, the longitudinal beams i5 and l-E are preferably arched upwardly at their forward portions as indicated at Also referring to Figure 4 the front and rear forward portion of the chassis and just rearwardly of the forward transverse beam i8. The double transverse beam has its vertical webs separated and its horizontal webs mutually, turned outwardly away from one another to better receive the swivel platform or turntable 26 which carries the caster wheel 25, which as shown in Figure' 5 is the single and sole wheel'that supports the forward portion of the machine, and is ar ranged centrally of the longitudinal median line of the machine with its platform and kingpin disposed beneath an upwardly displaced central portion of the double transverse beams 2!, 22.

At the rear the machine is supported upon two rear wheels 24 journaled upon the rear stub axle 23 which are appropriately mounted in the longitudinal beams 15 and IE or in other parts of the chassis framework.

The above parts constitute generally the wheeled chassis upon which the superstructure and body is mounted.

The superstructure comprises an openwork frame of longitudinal, transverse and. vertical beams, of which 21 and 28 (Fig. form the lower longitudinal beams and 29 and tlizthe. uppe-rpair of longitudinal beams; bothisets of beams .having the horizontal webs thereof disposed upward-- ly and inwardly and the vertical webs extending downwardly at the outer side lines of the machine.

As-appears in Figure, 5 a forward pair of transverse beams 32 are mounted between the longitudinal beams 21 and 28.:andwelde-dor otherwise aflixed thereto in such position that the beam. 3| is approximately above the beam 2d and thebeam 32 spaced above the forward transversechaxssis beam l8. Arearpair of transverse beamstil and 34 are disposed respectively above the chassis transverse beams it and. 21L These transverse beams are welded or otherwise securedto sets of vertical beams shown more particularly in Figure 8 ascomposing a pair offront vertical beams 35,

36, a pair of rear. verticalbeams. 3,1, 38and a pair ofintermediatebeams 39;, 48!. The. websof these vertical beams are. preferably disposedas shown. in Figure. 8.

These vertical beamstare also weldedor otherwise securedto, the, top transverse beams Si, 52 and 63. (Fig. l).

The superstructure as above described is adapted to. receive the-body which is composed generally of sheet meta-lside walls, frontand rear walls, atop with ice cream and beverage compartments therein, combined with refrigerating equipment.

The sheetmetal side wallsxoi the body are -indicated at and 42, the front wall at 4-3, the rear wall at d landthetop wall at 45.: ice cream: compartment 46 may extend substantially the full width of the machine at therearportion thereofasshown in Figure -8 and substantially vertically deep as shown in Figure -with thebottom of the compartment 46' extending down to the transe verse supporting beamstkwhich are aalow. level as. compared with thevv forwardpair ofitransverse beams 31 and 3.2. v

The ice cream compartment enclosed; by lateral head-insulating walls 4'! and 48, by vafront insulating wall 49Land a-rcar insulating wall 50. Within this compartment. 46 and within'itsinsulated are removably. or otherwise mounted. panels of refrigerating coils-5t, 52 and, 5,3, which are preferably disposed inithe sides and rear of this ice cream compartmentAt.

As shown in Figure 4, a heat-insulating bottom wall 5tv is disposed below a metal bottom 55. Asappearsin. Figure 8 the bottom SE-isslopedto a drain 55.. As shown-in Figure 4; this drain extends downto a lowpoint of the machine;v

The ice cream. compartment 4b is accessible through its upper endwhich. opens through the; ton Wall 45, oi.-1the:body.-. Ascover normallycloses ch: opening. 'lihis-coveris more. particularly shownin Figures 6,v and-7 as comprising two cover. sections; 5],. 58. havingappropriate knobs-o1: handholds and being hinged together centrally at 59 to enable one section to be lifted while the other remains in position. This cover preferably has a dependent flange 6B which fits within a raised annulus 64 which upstands from the top plate about the ice cream compartment 56.

Beverage syrup compartments 55, 66 are also mounted in the body of the machine in the forward portion thereof, the same being separated by'a partition 6.] and having a; common bottom 68; Such receptacles or compartments are refrigerated by the panel coils 69, 10, H and '12 which lie inwardly of the heat insulating sections 15 and iii/at the sides, H at the front and 49 at the rear. This insulating section 59 serves both the ice cream compartment 46 and the beverage compartments 65, 68. As shown in Figure 4, a bottom heat insulating section 13 lies below the beverage compartments 65, 65. The beverage compartments are not as vertically deep as the ice cream compartment, which condition is illustrated inFigure 4 and a. sectionM of. insulation lies forwardly of the lower part of the ice cream compartment 46 and connects with the bottom insulation fi l'andthe bottominsulation l3.

Dispenser. pumps 18' and 19 are. provided for each beverage syrup compartment of which there may be one or any appropriate number. The syrup discharge pipesare indicated at 8 3,. the same'having delivery nozzles. 8T poised above drippans 82 which are supported upon. the stainless steel top cover 45. Such drip-pans, as shown more particularly in Figure 5, have tubular necks 83 extending downwardly. from. central outlets. whichJnecks are adapted'to. slid'ably fit into tubularsleeve section 84. These sleeve sections may connect with a copper or other drain line 85' shown in Figure 8; or the sleeve section 85 may be disposed in a drain compartment 86 accessible through aside door 87', shown in Figure 1. Containers for the drippings may be introduced through thedoor 81 into the compartment Stand fit beneaththe sleeve section 84.

Bulkheads 88, 89 and 99. are. shownin Figure 4 as being respective-ly'beneath the beverage com.-

partments, the ice cream compartment and vertically arra-nged'back. of the space below the ice cream compartment.

The insulation forms. a substantial lining for the" sheet metal body, as. indicated to best advantage in Figure 8, and upon this insulationlis supported a plywood section 81!. which directly supports the stainless steel top cover 135.

Referring more particularly to Figure 9, the edge of the stainless steel cover 35 adjacent the beverage compartments overlaps. an outwardly extending; foot'flange 93 of araisedv annulus 82; the.v inner wall M of which overlaps the inner edge of the plywood section 91, and is in turn.

overlapped by a steel cover E5 which also overlaps the upper edge of the coil section F8. The beverage container wallsfihas an outturnedrim 9i overlying the annulus 92. The rim 9? has. a downturned outer flange-93 lying upon the outside of the annulus 92'. A downturned flange 9% is shown as having its; upper corner portionsroundedv with the metal of" the. top plate reduced coniormably and brought down-to completely envelope the edges of the plywood section I!) and to partly envelope the beams 29. This downturned portion of the top 45 also overlaps the body walls 42 and screws or other fastenings I86 pass through the overlapping parts and engage the beam v29.

Referring more particularly to Figure 11, a side wall ii and the front wall 43 of the body are shown as curved at the front corner portion of the machine and as overlapped outwardly of the vertical beam 35 with the wall di offset at I01 with the offset portion lying behind the overlapped part of the front wall 43. A rivet or other fastening liISpasses through the overlapped parts and screws the same to the beam 35.

' Referring more particularly to Figures 1 and 8, stiffener frame $59 for a door HE) is provided in a removable panel Ill aiiixed by appropriate fastenings to a side Wall of the body opposite a space 1 l2 (Fig. 1) wherein is installed a refrigeration unit for activating the various panel coils.

In Figure 1 is shown a pole socket H3 for receiving the lower end of an umbrella pole from which protection from rain and sun may be provided for the operating part of the device as well as for the attendant.

Referring more particularly to Figures 1, 2, 3 and 8, guardrails H4 are shown as extending substantially horizontally. along the sides of the body about midway the height thereof and spaced from the side Walls ll and 42, being carried by such side walls by means of outriggers or outstanding brackets H5.

[is shown in Fig. 2, the forward ends H6 and i i? of the guardrails extend downwardly in front of the front wall 43 in convergent relation and join with the ends of a bumper I 18 carried by the vehicle in the front lower portion thereof.

Referring more particularly to Figure 3, a back guardrail i 19- being a continuation of the rear end portions of the side guard rails I i i lies crosswise of the back wall 44 of the body, being spaced rearwardly therefrom. Handles I20 are also arranged at the back of the vehicle and their upper ends curved to the back wall M to which they are secured. These handles outstand from the back wall as indicated in Figure 1 and they intersect the rear guardrail lid, being preferably integral therewith. The lower ends of the handles 12d and the rear guardrail H9 are supported by brackets 1121 on the rear wall M. The shanks I22 of these brackets extend diagonally upward as shown in Figure 1.

Referring more particularly to Figure 2, louvers 12am any suitable number may be formed in the front plate 43 in a desirable design. This front plate 43 as shown more particularly in Figure 8 is bulged out centrally to a point or prow center line and preferably the same is on a diagonal line as indicated in Figure 4. The louver slots 528 furnish cooling air to the interior of space H2 and other refrigeration unit therein.

As appears in Figure 7, a cup dispenser I24 may be conveniently mounted in the top plate 45 adjacent the beverage dispensers.

In operation ice cream in package form is load 7 ed into the compartment 46 at an ice cream manture in and about the various compartments such as to preserve the contents thereof in a condition for prompt sale and consumption.

The vehicle thus constructed, equipped, supplied, and operated is pushed through the streets by means of the handles I20. Many of these vehicles may operate out of a central plant or point and are easily handled by a single operator. Such operator may easily push the vehicle to a desired'location, The caster wheel in front gives great flexibility in maneuvering the vehicle and in negotiating turns. When the desired location has been reached, a brake pedal MI is pushed to apply brakes to the vehicle for maintaining it against movement. A release pedal 132 (Fig. 3) provides for releasing the brakes when the motion of the vehicleis to be resumed. In this Figure 3 is also showna door I33 hinged to the rear wall 33 for giving access to a compartment in the ice cream compartment 46 which may be used for the storage of accessories needed in a vending business of the character involved.

The vendor makes sales of ice cream and beverages from the large supply of such merchandise aiiorded by the large capacity of this deep bodied vehicle with its. low slung chassis. The drainage is taken care of automatically so that the appear ance and sanitary condition of the vehicle is assured at all times.

This sanitation is further preserved by the device in Figures 12 and 13. By applying the hand 'to the thumb lift piece I30 and exertin an upward force thereupon, the arm H5 and its offset I21 may be swung from the dotted to the full line position of Figure 12 forcing the rubber or other stopper 128 into the mouth of the nozzle where it will become wedged by friction and remain closed until the thumb lift 130 is actively depressed; or the weight of the device may cause the same to gravitate to a closed position which is only opened when use is desired by the action on the part of the operator by depressing the opating piece 530.

It will be appreciated that the refrigerating unit, various compartments, coils and insulation are all grouped into relatively small compass for easy servicing and inclusion in a light weight, easily handled vehicle.

I have herein disclosed the best embodiment of the invention as known to me at this time but I reserve the right to make such changes and modifications as may fairly be construed Within the meaning of the appended claims.
